Sansevieria plant named ‘Black Limón’

ABSTRACT

The new variety Black Limón is part of the “long leaves” group of  Sansevieria  varieties and is a naturally-occurring mutation of the  Sansevieria trifasciata  variety ‘Laurentii’. It can reach 50-80 cm in length, with an average of approximately 3-5 leaves per plant. The plant is cylindrically shaped, with an erect growth habit and the arrangement of the leaves is in the form of a rosette. The new variety shows coloration very different from its parent variety and has variegated green leaves with light yellow-green colored margins. The new variety needs little water and is very drought tolerant.

Latin name of the genus and species of the claimed plant: Sansevieria trifasciata.

Variety denomination: Black Limón.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sansevieria plant, botanically known as Sansevieria trifasciata, of the family Ruscaceae, hereinafter referred to by the cultivar name ‘Black Limón’.

Sansevieria is a monocotyledonous and succulent, flowering plant which can be produced in either hard-leafed or soft-leafed varieties for interior use as a house plant or outdoor ornamental plant.

The new variety ‘Black Limón’ originated as a naturally-occurring mutation of the Sansevieria trifasciata variety ‘Laurentii’ (unpatented). The new Sanseviera ‘Black Limón’ was discovered and selected by the inventor, Marvin Gonzalez Villegas, as a single sprouting rare mutated plant in a plantation of Sansevieria trifasciata ‘Laurentii’, a controlled environment, in 2012 in Monterrey, San Carlos, Alajuela province, Costa Rica.

Asexual reproduction of the new Sansevieria cultivar ‘Black Limón’ by vegetative cuttings was first performed in 2012 in Monterrey, San Carlos, Alajuela province, Costa Rica and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘Black Limón’, which in combination distinguish this Sansevieria as a new and distinct cultivar:

-   -   1. Variegated foliage with different green tones on the         irregular bands, and light green colored margin bands in the         leaf blade     -   2. Wide and lanceolate leaves, supported in a rosette.     -   3. 50-80 cm plant height.     -   4. Erect plant habit     -   5. Needs little water and is very drought tolerant.

The new variety ‘Black Limón’ is considered a variety of “long-leaves” Sansevieria. The new variety presents an average of 3-5 leaves per plant when it reaches its maturity (between 8-12 months). The new variety has an erect growth habit and the entire plant can reach a height range between 50-80 cm. The leaves are narrow (3-5 cm average measured at the widest part of the mature leaf) and lanceolate, with a soft waxy texture. The blades are thin and slightly wavy. The plant has a cylindrical shape.

The new variety is very drought tolerant, adapts to conditions of light and shade (interior and exterior), and shows high tolerance level to antrachnose (Colletotrichum sansvierae) disease.

The leaf blade is dark green colored (RHS 134A), with non-uniform horizontal variegated bands in both sides of the leaves, moderate green (RHS 140B) colored, and also presents broad longitudinal light yellow-green (RHS149A) colored margins.

The variety ‘Laurentii’ gave rise to the variety ‘Black Limón’. The parent variety ‘Laurentii’ is also considered a “long-leaves” Sansevieria. ‘Laurentii’ shows a little more vigor than ‘Black Limón’, has a higher number of leaves per plant (5-6), with an average width of 4-6 cm (measured in the middle of the mature leaf.) The growth habit is erect and presents narrow leaves supported in a rosette. The entire plant can reach a size between 60-90 cm. The plant has, as for ‘Laurentii’, a cylindrical shape.

Plants of the new Sansevieria ‘Black Limón’ differ from plants of the parental cultivar, ‘Laurentii’ (unpatented) in the characteristics described in Table 1.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to the new Sansevieria ‘Black Limón’ is the Sansevieria ‘Laurentii’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Sansevieria cultivar ‘Black Limón’ showing the colors as true as is reasonably possible with colored reproductions of this type. Colors in the photographs may differ slightly from the color value cited in the detailed botanical description which accurately describe the color of ‘Black Limón’.

DETAILED BOTANICAL DESCRIPTION

The new Sansevieria ‘Black Limón’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant.

The aforementioned photographs, together with the following observations, measurements and values describe the new Sansevieria cultivar ‘Black Limón’ as grown in open-field conditions at Monterrey, San Carlos, Alajuela province, Costa Rica, under conditions which closely approximate those generally used in commercial practice. 24.5° C. during the day and 18° C. at night. Plants grow under natural light conditions.

This crop does not require constant fertilization, to increase production per area about 200 kg ha−1 N, 150 kg ha−1 of P and 100 kg ha−1 K are required, the production is closely related with soil conditions in which they are grown.

Color references are made to The Royal Horticultural Society Colour Chart Edition V, version 2, except where general colors of ordinary significance are used. The photographs and descriptions were taken during the rainy season in Monterrey, San Carlos, Alajuela province, Costa Rica when outdoor day temperature was 23° C. The age of the plants described is 8 months.
